This study was carried out to describe the prevalence of diabetic retinopathy and associated factors for development of DR in a cohort of patients routinely followed up in a hospital setting in Sri Lanka. An analytical cross sectional study was carried out using past patient medical records coupled with detailed clinical examination of eyes of Diabetic patients attending to Vijaya Kumaratunga Hospital, Seeduwa, Sri Lanka. Diabetic retinopathy was graded as Non proliferative diabetic retinopathy (NPDR), proliferative retinopathy (PDR) and macula oedema. Multiple logistic regressions was carryout to determine associated factors. In results there were 176 type 2 diabetic patients and 59 (33.5%) were males. Median age of the participants was 58 (25th and 75th percentiles 53 and 64) years. The overall prevalence of DR was 38.6% (35.6% among males and 40.2% among females). Commonest type of retinopathy among females was NPDR (22.2%) and among males it was both NPDR and (CSMO) Macular oedema (13.6%). Duration of diabetes was the only identified associated factor. (p = 0.024). In discussion the Prevalence of DR found from this study was higher than the reported value for Sri Lanka in 1993 and among the other Asian studies. Time duration was only identified as an associated factor for DR. Selection bias can be a limitation in this study since we evaluated a clinic attending compliant diabetics.
